Location: India | There is a one-page article on Arta Inkala's 'Toughest Sudoku' in today's Mumbai Mirror. I had given it a shot last night and was able to solve it in 21 minutes using guesswork. His challenge to everyone is to find a logical path of solving it, which he says can take weeks! I had given my views and feedback.
Those who live in Mumbai can read the article in Mumbai Mirror (page 8).
You can also read the article from the e-paper link: http://www.mumbaimirror.com/index.aspx?Page=article§name=News+-... |

Inkola had said 'The best players should be able to solve it within 25 minutes'. |

Location: France | Well, this puzzle was claimed to be "the toughest" several years ago ; things have changed now and there are lots of harder puzzles available. Anyway, finding a logical way to solve this one is a real challenge. Using guesswork, french player Yannick Meyapin solved it in 15/20 minutes during a competition.
Here is a puzzle which is theoretically even more challenging, with or without guesses :
. . . | . . . | . 3 9
. . . | . . 1 | . . 5
. . 3 | . 5 . | 8 . .
------+-------+------
. . 8 | . 9 . | . . 6
. 7 . | . . 2 | . . .
1 . . | 4 . . | . . .
------+-------+------
. . 9 | . 8 . | . 5 .
. 2 . | . . . | 6 . .
4 . . | 7 . . | . . .
